SP - Did I read it correctly that you have not spoken to an attorney before now? Why not?
You really need to go and hire one, and decide exactly what you ARE going to ask her for in a settlement, so that there will be no more cat-n-mouse "how could you do that to me" re: spousal support or a settlement. At 6 months into this, I hope you are ready and prepared to do this finally, it has gone on too long and is contributing to the problem. You seem to be too happy to stall, right along with her. So please stop that tendancy and decide - with an attorney - what you ARE going to ask for.
